JACQUARD NICHANISM FOR EIVIBROIDERlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 607,234, dated July 12, 1898.

Application filed J'nly 23, 1897. Serial No. 645,674. (No model.)

,T0 all whom it may concern.-

Be it known that I, JOSEPH A. GROEBLI, a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Jacquardv Mechanism, of which the following is a specification.

My invention relates to jacquard mechanism for embroidering-machines and other mechanism, and has for its object to produce an efficiently-operating device for stopping jacquard operated mechanism, especially jacquard operated embroiderin g machines, which stopping mechanism may be operated by hand or automatically.

My invention has special reference to improvements upon the jacquard mechanism set forth iu my United States Letters Patent No. 528,632, dated November4 6, 1894, to which reference is hereby made for greater certainty. In the machine set forth in my said Letters Patent I have shown divers devices for automatically stopping the mechanism in certain contingencies, and the structure ofthis my present invention is designed to more efficiently effect the stopping operations.

To these ends my invention consists in the lspecial matters hereinafter set forth and claimed.

My invention will be understood by referring to the accompanying drawings, in which- Figure l is a broken-away plan view of' a power-driven jacquard mechanism of the type and character of that shown in my said Letters Patent No. 528,632. Fig. 2 is abrokenaway side elevation of the same; and Figs. 3,

4, 5, and 6 are perspective views of some of moving racks J3. (See my Letters Patent vheretofore referred to.)

^ ments, and P is the shaft, operated by the failure of the shear-blades to close, in order to move the safety connection @24.

By referring to Fig. 1 it will likewise be noticed that I have provided another safety connection a, which, as in the case in the mechanism illustrated in my said patent, leads to the tracer which traces the pattern, as will be seen by referring to Fig. 40 of my said patent.

R is the band or cord which runs around the machine and which upon being pulled will effect the stopping or starting of the machine.

By referring to Fig. l it will likewise be noticed that adjacent to the shaft F, which serves to shift the double racks J3, dac., is a rising-and-falling pi'n or bolt F10, which serves to disconnect some of the doubleracks when it is desired to set the mechanism by the handle D20, as fully set forth in my patent aforesaid.

All these parts which I have just referred to and designated are similar, have similar functions to and operate similarly to the parts designated by the same reference-letters in my said patent, and it will be understood without further explanation that these parts `have connected with them correlated mechanism for effecting the full functions set forth in the said patent.

The shaft I carries the usual fast and loose pulleys 1 2, which may be belted to a countershaft or other source of power in any usual manner. The belt passes through the loop or eye 3 of a belt-shipper 4, which is shown as pivoted at 5 to a bracket 6 and providedl with a rearwardly-extending arm 7 notched at 8, to receive the cam 9 of an arm or camlever 10. This cam-lever, as is clearly shown in Fig. 4, is double-armed and is preferably made in the form shown--that is to say, is provided with a recessed hub 1l, apertured at 12, from which an arm 13 projects upwardly. This arm 13 may be provided with a locking lug or jog 14 and at or near its extremity with IOO ating-shafts D3 DL.

bearings 15 1G. The arm 10 may be hung loosely upon a stud 17 on the main frame A. This arm or cam-lever 10, as will be understood, by bearing against the tailpieee or arm 7 of the belt-shipper serves to shift the said belt-shipper to shift the belt from the fast to the loose pulley. This belt-shipper is likewise provided with a downwardly-projecting shoe 18, having its lip or edge 19 bent outward and projecting beneath the rim of the fast pulley 1, which maybe provided with a raised portion 2O of such thickness as to bear against the face of the lip 19 of the projecting shaft 18, so that the said lip 19 will act as a brake to bring the machine gradually to rest. A triparm 21 (best seen in Figs. 1 and 6) is loosely hung upon the stud 17, and is provided with a shaft 2.1, made rigid therewith, running across the machine and provided at its opposite end with an arm 23, with which the band R of the hand stopping mechanism is connected. The arm 13 carries a trip 24. (Shown clearly in Fi g. 5.) This trip 24 is provided with a stud 25, which is journaled in the bearing 16 of the arm 13, and is likewise provided with an arm 2G and with toes or abuments 27 28, one of which abutm ents 28 is rounded to allow the trip-arm 21 to slip past when it is moved to the left. The arm 13 is also provided with a coupling-piece 29, which has a stud 30 journaled in the bearing 15 of the arm 13. This coupling is provided with a step-shaped recess 31 31L and with a lip 32. It will be understood that both the trip 24 and coupling 29 swing freely in the sockets or bearings 16 15. Leading from the arm II is an oscillating rod or connector 33, (referred to in the claims as a moving part of the jacquard,) shown in i the present instance as provided with a hookshaped hand 3l, adapted to be engaged with the ledge or lip 32 of the coupling 2i). This rod or coupling receives an oscillating movement from the arm Il and is under direct con-` trol of a jacquard connection 7c, preferably of the type illustrated in my patent-aforesaid and referred to by the same reference-letter. The arm 13 is likewise provided with a laterally-extending projection 35, provided with an upwardly-projecting shoe This projection 35 is carried rigidly by the rod 13, and the shoe 3G extends upward into a slot in the arm 37, which is carried by the shaft of the handle D2", so that when the arm 13 is in its forward position, as hereinafter referred to, the hand setting mechanism cannot be lowered to engage with the pinions on the oper- Located adjacent to the arm 13 is a slide 38. This slide 38 has a horizontal reciprocating motion and is actuated by means of a spring 39. The slide is provided with an L-shaped slot 40, with which the toe 41 of a pivoted latch 42 engages. This latch 42 is carried upon a stud 43 and is connected at one end to the rod (L23, which runs to the tracer, and is likewise connected to the rod a2, which runs to the arm 2910011 the shaft P. The toe 41 of the latch 42 serves to hold the slide 38 in its retracted position, and the spring 39 serves to throw the slide forward until it strikes the abutment 14; on the arm 13.

The operation of the parts so far described is as follows: Itwillbe understood that swinging the arm 10 downward will cause the belt to be shipped and the machine stopped. This shipping may be effected in several ways. It may be done mechanically by moving the cord R, thereby swinging the arm 23 and its connected trip-arm 21 to the left. This triparm striking against the toe 28 of the trip swings the arm. 2G of the tr-ip from under the step 31L of the coupling and allows the coupling to fall until its lip 32 is in such a position as to be engaged by the hook 34c of the oscillating connection As this oscillating connection 33 moves to the right the coupling will slide under the hook, which will drop behind it, and as the oscillating connection moves forward it will pull upon the said coupling and carry the said coupling with it, thereby swinging the arm 13, which is connected to the coupling, to the left and swinging the arm 10 downward, thereby, as explained, shipping the belt. The stopping may also be effected from the jacquard, which, causing the connector 71; to be lifted, raises the connection 33 high enough to engage its hook 34; with the lip 32 of the coupling, and by thus engaging the hook 31k of the connection 33 with the said coupling causes the said coupling to be pulled forward by the connection 33, thereby swinging the arm 13 to the left and the arm 10 downward and shifting the belt-shipper to stop the machine. The shifting may also be effected automatically by the safety devices. One of these safety devices is the rod (L23, which, as before explained, is connected to the tracer of the embroideringmachine, so that should the tracer run off the pattern it will pull upon the rod @23, thereby swinging the latch 4.2 on the stud 4:3, disengaging the toe il of the said latch from the slot Vet() of the slide, which, being thereby released, will be pulled forward by the spring 39 and brought against the abutment 14 of the arm 13, thereby swinging the arm 13 forward, and consequently depressing the arm 10 and shifting the belt, as before. As soon as the belt has been shipped the slide 38, which has followed up the arm 13, colnes beneath the abutment 14I and locks the said arm 13 and the belt-shipper `firmly in place, so that it cannot be :moved until the said slide is released from under the abutment 14, which will be done by a competent mechanic when the parts which have been displaced are rearranged, or the slide 38 may likewise be released by means of the rod a2, which also swings the latch 42 when actuated. This rod am is, as before explained, moved from the shaft P, which shaft P is actuated only when by reason of some imperfection in the pattern too many jacquard-needles are selected. When this occurs, the shaft I is rocked, thereby swinging the arm 4.4:, push- IOO IIO

ing'upon the connection @21 and causing the same to swing the latch 42, whereupon the slide 3S will be sprung forward by the spring 39 and the parts will act as just explained.

Having described the stopping device, I will nowk proceed to more minutely describe the hand-operated mechanism for moving` the racks to move the embroidering-frame. This hand-operated mechanism, as will be understood by referring to my patent aforesaid, comprises a handle D20, supported on a yoke D10, which carries a pinion D18, which gears with pinions D0 D10, each on one of the operating-shafts D3 I)4 of the mechanism, Vand at times with a pinion D17, which is carried upon a stud and meshes with the pinion D10. The handle, yoke, and pinion D1,s may be raised and lowered, and when lowered engages either with the pinions D0 D10 or with the pinions D17 D0. The shaft of the arm D20 also carries a plate 44, which is apertured at 45 and at 4G for the passage of the shaft D2 when the arm, yoke, and pinion are lowered. The shaft of the arm D20 is likewise provided with the arm 37, whose lower edge is slotted for the passage of the shoe 30. The shaft D1 of the pinion D0 passes through'this arm, which is loose thereon, and the shaft carrying the arm D20 and the pinion D10 swings on this shaft D4 as a pivot7 being supported by the arm 37, which is freely movable up and down on this shaft. The shaft carrying the arm D20 is likewise provided with a plate 47, located above the plate 44, a pin on the rear end of the arm A24 projecting between the plates 44 and 47. This arm A21, as explained, is pivoted at 49 and extends into a notch on the slide or bolt F10.

The parts just described are all locked from operation by reason of the abutment of the lower end of the arm 37 against the shoe 3G. When the machine has been stopped, the arm 13 will have swung so far forward as to move the shoe 36 in the slot of the arm 37 until the tail 36 of the shoe 3G has passed from beneath the arm 37, when the arm 37 may be swung on its pivot-shaft D4. Now if -it be desired to move the frame by hand the arln 37 may be swung on its pivot until one of the holes 45 or 46 is over the shaft D3 when the arm 37, the arm D20, and the pinion carried by its shaft may be moved downward to engage the pinion D18 with the appropriate gear-wheels. At the same time the plate 47 will bear against the arm A21, thereby swinging it on its pivot and raising its outer end and lifting the bolt F10, so as to disconnect apair of the racks in order that the device may be moved by hand to move the fabric-frame. /V hen the parts have thus been lowered, the arm 37 is in the path of the return movement of the shoe 3G, so that the parts which ship the belt cannot be restored to their initial positions to start lthe machine until the hand-operated mechanism for moving the embroidering-frame has been restored to its original position. It will be observed that when the arm 37 has been swung into position to engage the pinion D18 with either pair of pinions for driving the shafts D3 D4 a hole 45 or 46 will be over the shaft D2, so that as the arm 37 is lowered the shaft D3 will pass through the said hole; but when the arm 37 is in its intermediate or mid,-

dle position, as shown, t-he arm cannot be low-v ered, as a solid part of the plate 44 will come against the shaft D2, so that the arm can only be swung on its pivot-shaft D1 and lowered when the shoe 3G is not in the slot of the arm 37.

It will thus be seen that the hand-operated mechanism for moving the embroideringframe and the stopping mechanism for the machine are so interlocked and correlated that one cannot be operated unless the other is in an inoperative position.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-
